Application filed December 8, 1890. Serial No. 373,859. (No model.)

.T all whom it may concern.-

Be it knownv that we, JOHN CHADDERTON and ALFRED HITci-IINs, bot-hcitizens of the United States, and residents of Philadelphia,

Pennsylvania,have invented certain Improve- .principal object being toConstruct a machine applicable to the twisting' ot' a form of chenille,although it may of course be employed for yarns or strands of anycharacter.

In the accompanying drawings, Figure l is a side view ot a twisting-andwinding machine constructed in accordance with our in- Fig. 2 is a planview of the same. Fig. 3 is a transverse section on the line 1 2,Fig. 1. the direction of the arrow, Fig. l. Fig. 5 is a longitudinalsectional v-iew of one of the spooling mechanisms detached from themachine. Fig. 6 is a-perspective view of one of the twisting-spindles.Fig. 7 is an enlarged view of the head of one of the twisting-spindles.Figs. 8 and 9 are views of details, and Fig. lO is a view of amodification.

The machine, as shown in Fig. 1,is divided practically in two parts, the'portion Acarrying the twisting mechanism and the portion A carrying thespooling mechanism, but both portions are drivenfrom the commondrivingshaft C.

XVe will tirst describe the twisting mechanism. The machine shown in thedrawings is designed to twist twenty-four ends of yarn,

although more or less than this number may be twistedA by multiplying ordecreasing the number of twisters and spoolers. Mounted on the frame Aare a series of hollow twisting-spindles B. (Shown in detail in Figs. 6and 7.) These spindles are adapted to bearings a a on the frame, andeach spindle is provided with a gear-wheel b, which engages withintermediate gear-wheels b', as shown` by dotted lines in Fig. 3, sothat all the gears of the spindles are in train. Motion is imparted tothe train by a pinion c', mounted on the shaft c, which is driven fromthe main shaft C bya belt c2, passing around a wheel c3 on the mainshaft and around awheel c4on the shaft c. Q As the twisting-spindles areall of the same construction, a detailed descrip- Fig. et is an endelevation looking in' ing its opposite ends secured in the `head B is awiredZ, the coils of which, however, are of such size as to permit thefree rotation of the roller d. In the outer end of the head B is an eyed3, through whichth'e twistedyarn is delivered to the winding-frames.The yarn enters at the mouth b2, passing through the spindle, is coiledonce around the roller cl in the spaces between the coils of the wired2, and from thence passes out through the eye d3, so that as thespindle is revolved the yarn is twisted.

Mounted in the standards A3 of the frame A are a series of sleeves D. toeach of which is secured a pulley D', rotated by a belt passing over thepulley and over a drum E, each spindle heilig driven from said drum byan independent belt, and the wheels or pulleys on the spindles are sostaggered that their belts will clear each other, as will be understoodon reference to the accompanying drawings.

Passing through the sleeve D and rotating therewith is a spindle D2,having a central passage for the yarn delivered from the twisters andcarrying at one end a flier e, constructed in any suitable manner, theradial Passingl around this roller in a helical form and hav-Y armof'theiiier in the present instance having a passage e2, through whichthe yarn passes and is delivered to an eye c3 at the end of the flier.The outer end of the spindle is provided with a grooved collar f,rotating freely in a bearing f on one of the transverse bars of areciprocated frame F, so that as the flier is rotated with the sleeve Dit may be moved to and fro by the frame F to effect an even wind on thespool or bobbin. This frame F comprises two transverse bars f2f2,secured together by bolts g and sliding on guide-bars g on theframe-work.

Mounted on the frame of the machine is a transverse shaft G, carryingapulley G', over which passes a belt G2 from asmall pulley on the maindriving-shaft C, and on said shaft G is a belt-pulley g2, over whichpasses abelt IOO g8 to a belt-wheel G4 on a transverse shaft G. On theshaft G is a worm h, gearing with a worm-wheel h on a vertical shaft H,adapted to bearings on the frame A3. Secured to this shaft H is a camh2, of the character shown in Fig. 8, which acts on a pin h3 of the barh4, connected to a lever f3 on the rock-shaft H', said rock-shaft beingmounted vertically in bearings projecting from the frame A' and providedwith a series of arms h5, connected to the series of frames F.

To provide for the return of the frames after being moved in onedirection by the cam h2, I place springs g2 on the guide-bars g betweenthe fixed frame-of the machine and the frames F, or, if desired, the camh2 may be made in the form of a grooved cam, so as to move the fram espositively in both directions.

Thus it will be seen that as the shaft H revolves the cam h2 acts tovibrate the rockshaft H moving the eye e3 of the flier over the face ofthe spool J, on which is wound the chenille or other yarn.

On the section A4 of the frame A are mounted small shafts I, carryingspools J, on which the yarn is wound by the liier. On each shaft is abelt-wheel t', driven by a belt t" from a drum or pulley 1 on atransverse shaft I2, this driving mechanism being similar to thatemployed for rotating the sleeves D, as already described. The spool YJis slipped over an extension t2 of this shaft I, and is coupled to saidshaft by a pin i3, adapted to a camgroove t4 in the plate i5 on the endof the spool, as clearly shown in Figs. 5 and 9, so that. as the shaft Irevolves it will carry the spool on this shaft at the same speed; but toremove the spool from this shaft all that is necessary is to turn thespool in the opposite direction, the spool freeing itself from the pinby its cam-slot. As the diameter of the spool varies with the amount ofyarn wound upon it, the speed of rotation of such spool is graduallylessened as the winding proceeds, a description of the mechanism foreffecting such gradual change being as follows:

Referring to Figs. l and 4, K is a shaft having a belt-wheel 7c, aroundwhich passes a beltvk from a belt-pulley k2 on the drivingshaft C. Onthe shaft K is a cone-pulley L, the belt Z from which passes up and overa cone-pulley L', tapered in a direction opposite to that of thecone-pulley L, as clearly shown in Fig. 4. On the shaft L2 of theconepulley L is a belt-pulley Z, around which passes a belt Z2 to abelt-Wheel l3 on the shaft I2. The belt Z on the two cone-drumsis movedalong gradually by a shifter M, one end of which engages the belt Z, theother end engaging a screw M on the shaft M2. Mounted on the end of thisshaft is a ratchet-wheel m, and engaging with this ratchet arespringpawls fn, pivoted to a reciprocating bar N, guided at one end bythe shaft M2 and connected at its other end to an arm n on therock-shaft H', so that as the rock-shaft vibrates it will reciprocatethe bar N, the pawls of which engaging with the ratchet will turn thescrew-shaft and feed the belt along the .cone-drums, graduallyincreasing or diminishing the speed of the spools, as may be desired.The shaft E is driven from a beltwheel p by a belt p', which passesaround a belt-pulley 192 on the shaft E', so that the lspindles D2 aredriven at a regular speed.
